Final answer:
Mixtures are not chemically combined together, they are physically mixed. Components of a mixture can be separated by physical means. Chemical combinations involve a chemical reaction and the resulting substances have different chemical properties.
Step-by-step explanation:
Mixtures are not chemically combined together. A mixture is a combination of two or more substances that are physically mixed together but retain their individual chemical identities. In a mixture, the components can be separated by physical means such as filtration or evaporation.
For example, a mixture of salt and water can be separated by simply evaporating the water, leaving behind the salt. This is because salt and water do not chemically react with each other when mixed.
In contrast, a chemical combination involves a chemical reaction where the substances combine to form new substances with different chemical properties and identities. In a chemical combination, the components cannot be easily separated by physical means.
